But there are still some differences as well, which may or may not be important in your search for information.<\/p>    <h3 class=\"wp-block-heading\">Similarities<\/h3>    <p class=\"wp-block-paragraph\">Hydrogen peroxide and carbamide peroxide:<\/p>    <ul class=\"wp-block-list\"> <li><strong>Are oxidizing agents:<\/strong> Both hydrogen peroxide and carbamide peroxide are reactive when they are exposed to oxygen. It&#8217;s this oxidizing process that makes them break down stains, leaving teeth whiter and brighter. <\/li>    <li><strong>Whiten teeth<\/strong>: Both chemicals can be effective in whitening teeth, sometimes with very noticeable results, depending on the method and the concentration used.<\/li>    <li><strong>May cause sensitivity:<\/strong> Whitening procedures often cause sensitivity, but there is typically no difference in the amount of sensitivity you will notice, whether you are whitening with hydrogen or carbamide peroxide. <\/li>    <li><strong>Don&#8217;t cause rebound<\/strong>: Rebound is when teeth appear whiter right after a whitening procedure, normally caused by dehydration. Neither carbamide peroxide nor hydrogen peroxide cause rebound. <\/li> <\/ul>    <p class=\"wp-embed-aspect-16-9 wp-has-aspect-ratio wp-block-paragraph\">     <div class=\"dentist-tip\">          <div class=\"dentist-tip__title\">             Ask a dentist: <strong>Why are my teeth turning yellow when I brush all the time, don\u2019t drink coffee and don\u2019t smoke?&nbsp;<\/strong>        <\/div>          <div class=\"dentist-tip__content\">             <\/p>    <p class=\"wp-block-paragraph\">Tooth discoloration is unfortunately a natural part of the aging process as the enamel on teeth wears down over time due to chewing. This exposes the yellow-colored dentin layer underneath and is the main cause of teeth appearing yellow. But of course, teeth can also become discolored from eating or drinking certain food or beverages and tobacco use.<\/p>    <p class=\"wp-block-paragraph\">There are several different options for temporarily restoring the whiteness in your teeth including products that use the ingredients mentioned in this article. As bleaching agents, both hydrogen peroxide and carbamide peroxide are equally effective. Patients treated with carbamide may see quicker results but after a few months go by there is no discernible difference.<\/p>    <p class=\"wp-block-paragraph\"><strong>Sonya Alvarado, DDS<\/strong>, <strong>Full Smile Dental<\/strong><\/p>    <p class=\"wp-block-paragraph\">        <\/div>      <\/div>      <\/p>    <h3 class=\"wp-block-heading\">Differences<\/h3>    <p class=\"wp-block-paragraph\">There are lots of similarities between <strong>hydrogen peroxide and carbamide<\/strong> peroxide, but what about the differences? Let&#8217;s have a look at some of the main differences between them.<\/p>    <ul class=\"wp-block-list\"> <li><strong>Chemical composition: <\/strong>Hydrogen peroxide consists of hydrogen and oxygen. Carbamide peroxide is made up of hydrogen peroxide and urea (carbamide). So carbamide peroxide actually contains hydrogen peroxide in it. <\/li>    <li><strong>Speed:<\/strong> Hydrogen peroxide breaks down much quicker than carbamide peroxide, with most of its whitening ability released within the first 30 to 60 minutes. Carbamide peroxide releases half of its whitening power in the first 2 hours of treatment and then continues to be active for up to 6 hours. Ultimately, this means that products with hydrogen peroxide are worn for shorter periods of time during each treatment, but this doesn&#8217;t change the length of an actual course of treatment. <\/li>    <li><strong>Shelf-life:<\/strong> Carbamide peroxide has a longer shelf life than hydrogen peroxide, but hydrogen peroxide&#8217;s shelf-life can be extended with refrigeration.<\/li> <\/ul>    <h2 id=\"pros-and-cons-of-each\" class=\"wp-block-heading\" \"pros-and-cons-of-each\">Pros and cons of each<\/h2>    <p class=\"wp-block-paragraph\">As we&#8217;ve established, both carbamide peroxide and hydrogen peroxide <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/10986827\/\" target=\"_blank\" rel=\"noreferrer noopener\">are effective teeth whiteners<\/a>, but each one has its pros and cons, which we&#8217;ll take a closer look at now. <\/p>    <h3 class=\"wp-block-heading\">Pros and cons of teeth whitening with hydrogen peroxide<\/h3>   <div class=\"wp-block-wptb-table-block\"><div class=\"wptb-container-legacy\" data-table-id=\"49354\">     <table class=\"wptb-preview-table wptb-element-main-table_setting-49354 edit-active\" data-reconstraction=\"1\" style=\"border: 1px solid rgb(209, 209, 209);\" data-wptb-table-tds-sum-max-width=\"263\" data-wptb-cells-width-auto-count=\"2\" data-wptb-table-directives=\"eyJpbm5lckJvcmRlcnMiOnsiYWN0aXZlIjoiYWxsIiwiYm9yZGVyV2lkdGgiOiIxIiwiYm9yZGVyUmFkaXVzZXMiOnsiYWxsIjpmYWxzZX19fQ==\" data-wptb-extra-styles=\"LyogRW50ZXIgeW91ciBjdXN0b20gQ1NTIHJ1bGVzIGhlcmUgKi8=\" role=\"table\" data-table-columns=\"2\"><tbody><tr class=\"wptb-row\"><td class=\"wptb-cell\" data-y-index=\"0\" data-x-index=\"0\" style=\"border: 1px solid rgb(209, 209, 209);\" data-wptb-css-td-auto-width=\"true\"><div class=\"wptb-text-container wptb-ph-element wptb-element-text-31\" style=\"color: rgb(74, 85, 104);

Even though it doesn&#8217;t contain peroxide, which is the base of most teeth bleaching products, it has been proven to be just as effective as peroxide products. <\/p>    <p class=\"wp-block-paragraph\">PAP works to whiten teeth by going through the enamel layer and breaking down color-holding molecules, oxidizing stains, and thus lightening the color of the tooth, just like hydrogen peroxide and carbamide peroxide. <\/p>    <p class=\"wp-block-paragraph\">The difference is that peroxides release free radicals during the whitening process, and these can cause sensitivity and in some cases damage your teeth and gum tissue.<\/p>    <p class=\"wp-block-paragraph\">PAP, on the other hand, doesn&#8217;t release free radicals during the stain oxidization process, and thus some dentists consider it to be safer, and the likelihood of experiencing sensitivity is all but eliminated. <\/p>    <p class=\"wp-block-paragraph\">We have a complete guide to <a href=\"https:\/\/www.dentaly.org\/us\/teeth-whitening\/pap-teeth-whitening\/\" data-type=\"page\" data-id=\"45953\" target=\"_blank\" rel=\"noreferrer noopener\">whitening teeth with PAP<\/a> if you are interested in learning more. <\/p>    <h2 id=\"best-products-for-teeth-whitening\" class=\"wp-block-heading\" \"best-products-for-teeth-whitening\">Best products for teeth whitening<\/h2>    <p class=\"wp-block-paragraph\">Now let&#8217;s go through our top picks for teeth whitening using hydrogen peroxide, carbamide peroxide, and PAP. <\/p>   <div class=\"wp-block-image\"> <figure class=\"alignright size-medium is-resized\"><img decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/www.dentaly.org\/us\/wp-content\/uploads\/sites\/16\/2022\/08\/snow-original-whitening-kit-wands-300x300.jpg\" alt=\"hydrogen peroxide vs carbamide peroxide\" class=\"wp-image-61068\" style=\"width:205px;height:205px\" srcset=\"https:\/\/www.dentaly.org\/us\/wp-content\/uploads\/sites\/16\/2022\/08\/snow-original-whitening-kit-wands-300x300.jpg 300w, https:\/\/www.dentaly.org\/us\/wp-content\/uploads\/sites\/16\/2022\/08\/snow-original-whitening-kit-wands-150x150.jpg 150w, https:\/\/www.dentaly.org\/us\/wp-content\/uploads\/sites\/16\/2022\/08\/snow-original-whitening-kit-wands-768x768.jpg 768w, https:\/\/www.dentaly.org\/us\/wp-content\/uploads\/sites\/16\/2022\/08\/snow-original-whitening-kit-wands.jpg 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption class=\"wp-element-caption\">Snow teeth whitening<\/figcaption><\/figure> <\/div>   <h3 class=\"wp-block-heading\">With hydrogen peroxide<\/h3>    <p class=\"wp-block-paragraph\">Snow is a much-beloved at-home teeth whitening kit that uses LED light technology to activate their whitening gel.

With Smile Brilliant, you get custom-made whitening trays and professional-strength whitening serum with carbamide peroxide. Since carbamide peroxide takes longer to release its whitening powers, it is recommended that you whiten for up to 3 hours for each treatment. <\/p>    <p class=\"wp-block-paragraph\">Because Smile Brilliant is the same treatment you would get from your dentist, it is capable of whitening years and years of the deepest stains.

They are both effective and safe to use, as long as you follow the instructions. <\/p>    <p class=\"wp-block-paragraph\">The main difference is that hydrogen peroxide releases its whitening power faster than carbamide peroxide. Carbamide peroxide, which is a combination of hydrogen peroxide and urea, or carbamide, takes longer to release its whitening power. <\/p>    <p class=\"wp-block-paragraph\">Another ingredient being used more often in whitening products is PAP, which doesn&#8217;t release any free radicals during the oxidization process, and therefore, causes no sensitivity, which is a problem some people experience with hydrogen peroxide and carbamide peroxide. <\/p>    <h2 id=\"faqs\" class=\"wp-block-heading\">FAQs<\/h2>    <h3 class=\"wp-block-heading\">What is the difference between carbamide peroxide and hydrogen peroxide?<\/h3>    <p class=\"wp-block-paragraph\">The main difference is that carbamide peroxide takes longer to break down than hydrogen peroxide. Carbamide peroxide also has a longer shelf-life than hydrogen peroxide. Both are effective and safe tooth bleaching solutions. <\/p>    <h3 class=\"wp-block-heading\">Where can you buy carbamide peroxide?<\/h3>    <p class=\"wp-block-paragraph\">Unlike hydrogen peroxide, which you can buy over the counter in low concentrations, carbamide peroxide must be bought as part of a tooth whitening treatment, like <a href=\"https:\/\/www.smilebrilliant.com\/product\/teeth-whitening-trays\/?ref=8950&amp;utm_source=dentaly&amp;utm_medium=article&amp;utm_campaign=general\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Smile Brilliant<\/a>.<\/p>    <h3 class=\"wp-block-heading\">Which works better, hydrogen peroxide or carbamide peroxide?<\/h3>    <p class=\"wp-block-paragraph\">Hydrogen peroxide and carbamide peroxide achieve the same whitening results. Hydrogen peroxide is often used in at-home whitening kits because it doesn&#8217;t require you to wear it very long. Carbamide peroxide is more common with professional whitening treatments because it requires a longer application. <\/p> <div class=\"socials_share\"><ul class=\"share-buttons\">     <li
